Abstract

The utility model discloses an anti-overflow and anti-odor floor drain, which consists of a cylinder body (1), an upper mouth cover (2), a baffle plate (3), a sealing lining (4), a counterweight (5), and a support frame (6). and other components, a perforated upper cover (2) is provided on the cylinder body (1), a baffle plate (3) with the same shape as the lower opening is provided on the cylinder body (1), and the baffle plate ( The other end of 3) is connected to a counterweight (5), and the kinetic energy of the water can be used to easily open the baffle (3) to discharge sewage. After the water flow is discharged, under the gravity of the counterweight (5), the baffle (3) 3) It closes quickly and keeps closed at any time. Because it adopts the technology of blocking from the front end of the pollution source, it can more effectively block the peculiar smell and low-pressure return water coming from the sewer pipe.

Description

An anti-overflow and anti-odor floor drain

technical field

The utility model relates to a floor drain for indoor and outdoor drainage, in particular to a floor drain with functions of preventing overflow and deodorization.

Background technique

It is found through retrieval and query on the Internet and published patent documents that there are many floor drains with anti-overflow and anti-odor functions in the current commercially available and published patent documents, but there are certain technical defects in these floor drains. It is mainly manifested in two aspects. One is the complex structure, curved flow path, small flow section, and easy blockage. As shown in ZL200620057828.1, due to the poor working environment of the floor drain, the fine debris mixed in the sewage cannot pass through the curved opening smoothly, and will accumulate and block. Its two is to have taken rusty and fatigue damage metal member such as spring etc. on structural technology, makes its service life shorten. As shown in ZL200520046691.5, the device uses the pressure of the spring to close the blocking plate, so the resistance caused by the pressure of the spring must be overcome first when draining water, and the water can be drained smoothly only when the gravity of the water is much higher than the pressure of the spring , if the spring is rusted or deformed due to fatigue, its sealing function will be lost.

Above-mentioned two kinds of devices are owing to the unreasonable reason of structural design, and its defect is difficult to overcome.

Contents of the invention

The utility model optimizes the above problems and provides a floor drain with simple structure, large flow diameter, no metal components, flexible opening and closing, and reliable sealing at the front end of the pollution source.

The utility model proposes a technical solution for the above-mentioned problems: a perforated top cover is provided on the upper mouth of the circular cylinder; On the oblique plane, there are two supports at the lower part of the oblique plane, and a round hole is provided on the support; a baffle plate with the same shape as the lower opening of the circular cylinder is provided, and the other end of the baffle plate is connected with a counterweight A small cylinder is arranged on both sides of the baffle plate, and the small cylinders are respectively embedded in the round holes on the support body, and a flexible sealing lining is bonded on the baffle plate.

The beneficial effects of the utility model are: the structure is simplified, the manufacturing cost is reduced, the circulation diameter in the cylinder is relatively large, and it can be drained straight through without accumulating residual sundries and blockage, and all components are made of plastic parts, so there is no problem of metal components not adapting to the humid environment. The phenomenon of rust damage, especially the design of the sealing baffle at the bottom, more effectively enhances the ability of the non-return sealing.

Detailed ways

Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of anti-overflow and anti-odor floor drain of the present utility model is composed of cylinder body (1), upper mouth cover (2), baffle plate (3), sealing liner (4), counterweight (5) ), support frame (6) and other components. The upper mouth cover (2) is a circular plate body, and the plane of the plate body is porous to facilitate water intake and block larger debris; the cylinder body (1) is a hollow cylinder, and a stopper step is provided at the upper water inlet end , so that the upper mouth cover (2) is put in, in the middle of one side of the cylinder, a beveled plane inclined outwards at an angle of 50 degrees and extended inwards is set, the end of the lower drain is in the shape of a horseshoe, and two sides of the lower part of the beveled plane end, connect a rectangular support frame (6) respectively, a circular hole is set on the support frame (6), and the small cylinder on the baffle plate (3) is embedded in the circular hole to make it a twisted connection; the baffle plate (3) And the counterweight (5) is an integral structure, with the small cylinders on both sides as the balance fulcrum, one end of the counterweight (5) will be slightly heavier than this end of the baffle plate (3), so that when the water flows through, the kinetic energy of the water will be used. The baffle (3) can be easily opened, and the water flow will quickly pass through the cylinder and be discharged into the pipe. After the water flow is discharged, its kinetic energy disappears, and the baffle (3) quickly returns Closed and kept closed at any time, in addition, the utility model adopts the technology of sealing from the front end of the pollution source, so it can more effectively block the peculiar smell and return water with low pressure in the sewer pipe.
